Marine litter
Marine litter is a global problem that affects every ocean of the world. Litter is an environmental, human health and socio-economic problem that is a symptom of a highly disposable society.

With worldwide growth in the amount of solid litter thrown away every day and slow rates of degradation, the amount of litter present in the marine environment is increasing.

Global modelling of surface water quality: a multi-pollutant approach 
Carolien Kroeze, Silke Gabbert, Nynke Hofstra, Albert A Koelmans, Ang Li, Ansje Löhr, Fulco Ludwig, Maryna Strokal, Charlotte Verburg, Lucie Vermeulen, Michelle TH van Vliet, Wim de Vries, Mengru Wang and Jikke van Wijnen In many world regions the availability of clean water is at risk.
Pollution of rivers and coastal seas poses a threat to aquatic ecosystems and society. Here, we review representative examples of mathematical models that simulate pollutant flows from land to sea at global and continental scales. We argue that a multi-pollutant modelling approach would help to better understand and manage water quality issues. Pollutants often have common sources and multiple impacts. Most existing spatially explicit models, however, focus on one type of pollution only. A new generation of models is needed to explicitly address the combined exposure of surface waters to multiple pollutants. Such models could serve as a basis for integrated water quantity and water quality assessments.

His area of expertise covers toxicity of environmental pollutants including nanoparticles and microplastics, oxidative stress, carcinogenesis, neurotoxicity, regeneration and electron- and fluorescence microscopy.

Inneke Hantoro has her Master degree on Food Science (The University of Melbourne, Australia). She is a full time lecturer at the Department of Food Science, Soegijapranata Catholic University, Indonesia. Her teaching and research activities are in areas related to food safety and quality, such as toxicology and food safety, food quality assurance, and risk analysis courses. Currently, she is a PhD student at Department of Science, Faculty of Management, Science & Technology, Open Universiteit, the Netherlands. Her research is focused on the risk of microplastics in Indonesian coastal areas for coastal seafood species and human health.

Education

May 2017: our second Massive Open Online Course on Marine Litter

To create global awareness, The United Nations Environment Programme (UNEP) in cooperation with the Open University of the Netherlands, launched a Massive Open Online Course (MOOC) on Marine Litter in 2015. This highly successful MOOC with more than 6.500 students enabled its participants to stimulate leadership and offered opportunities for actionable and change oriented learning related to marine litter within the framework of the Global Partnership on Marine Litter.

Because of its success, this free course was rolled out again.

This second Massive Open Online Course on Marine Litter (MOOC) aimed to help almost 3.000 students, through action learning, on ways to apply strategies in the real world. Moreover, this course assisted policymakers, practitioners, and managers who wish to connect with other professionals to enhance their knowledge of marine litter issues.

The MOOC was available in two tracks: a leadership track and an expert track. It started in May 2017 with the Leadership track taking place over a course of 2 weeks. Those students who wished to remain in the course continued to the Expert track, which was completed in July 2017 (total of 8 weeks).

A certificate of participation could be obtained by students after their completion of both the Leadership track and the Expert track. Students also received free access to all course materials on a 24-hour online platform.

This thesis was awarded with the prize for the best science resarch from members of the science community at the Open Universiteit Eureka! Festival. 29 November 2015 Ansje Löhr presented at the Eureka! Festival in Amsterdam within the context of the Dutch National Research Agenda 'Plastics in the environment address worldwide'.

Partners and projects

Plastic waste in the aquatic environment can vary greatly in size, i.e. from the nanometre to the meter scale. The larger macro plastics are mainly associated with visual pollution and forms of physical stress (e.g. entanglement and blocking of inlets), whereas the smaller micro plastics are mainly associated with food chain accumulation and toxic effects. Macro plastics typically originate from dumping, littering and wind dispersal, whereas micro plastics typically originate from the degradation of macro plastics and specific applications, e.g. micro beads in medicines and personal care products.

The need to address plastic pollution in aquatic environments has been recognized worldwide, e.g. in the United Nations Environment Programme (UNEP) Honolulu Strategy. The Department of Science cooperates with several organizations. Research topics focus on micro- and macroplastics pollution in rivers and seas and include detection methods, modelling, effects and preventive measures.

Global Partnership on Marine Litter

The Faculty of Management, Science & Technology of the Open University of The Netherlands is part of the Global Partnership on Marine Litter (GPML), a global community of stakeholders dedicated to reducing the sources and impacts of marine litter worldwide.
